What Is a Yeast Infection?
2. Causes
There are different types of yeast that can cause infections, but the variety most often responsible for causing a vaginal yeast infection is candida albicans. Candida albicans is usually always present in the vagina anyway as the vagina contains a balance of microorganism including yeasts and bacteria.
These microorganisms usually exist in a balance that causes no harm, and can even be beneficial. However, the balance can sometimes be lost, and it can result in candida albicans proliferating beyond its usual levels. There are various reasons why this imbalance can occur, including the use of some medication, pregnancy, diabetes, and a weakened immune system.
